STEEL WHEEL FOR TRUCKS.

Application filed March 15, 1920. Serial No. 365,700.

To all whom it may concern:

Be it known that we. GEORGE VVAL'IHEH and PETER W. KLINGER, citizens of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Steel VVheelsfor Trucks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to steel wheels for trucks of the general character shown in our Patent No. 1,393,928, issued Oct. 18, 1921, on an application filed Feb. 21, 1920.

These wheels are of novel construction and an improved type of cast wheels, having particular reference to the convenience or facility with which the casting operations may be performed.

It is an object of the present invention, as of our earlier invention above referred to, to provide a wheel made up of several units, the cast parts of which are more readily adaptable to molding and casting, because of their simpler form, than entire wheels I cast integrally.

In the present construction, as also in the earlier construction referred to, the hub and spokes are cast integrally, being made preferably in standard sizes and adapted therefore to have various types of detachable rims mounted thereon.

These wheels, as shown and described in our earlier application, have preferably an improved form of reinforced hub, provision being made in the design and construction of the hub for maximum strength for given weight and dimensions, the wheels, equipped with suitable tires, being adapted for both light and heavy loads.

The present invention, as distinguished from our earlier invention, has a demount able rim instead of a detached rim adapted to be permanently mounted on the wheel.

The demountable rim, as here shown, has suitable means for quick mounting and demounting of the rim relative to the wheel. While a preferred form of mounting devices is shown, it will be understood that it is contemplated in the invention to use any suitable devices for this purpose, the construction here shown in this respect being for illustrative purposes only.

with valve stem slots similar to the slots shown in our co-pending application for patent, Ser. No. 338.575, filed Nov. 17th, 1919, but modified to meet the requirement of the present invention. \Vhile the rim may, of course, be constructed and used without these slots, it has been found to be of considerable advantage in manufacturing, to form the slots in the rim of the integrally-cast hub and spokes.

As far as we are aware the two forms of construction shown in this and our earlier application above referred to, are broadly new in this art, the underlying principles of the invention being the integrally formed hub and spokes and suitable detached rims adapted to be permanently mounted on the inner wheel structure by riveting or welding, as shown in the earlier invention, or to be demountably secured thereon, as shown in the present invention. We claim the invention broadly, therefore, without limitation as to details of construction and arrangement.

Referring to the drawings;

Fig.' 1 is a side elevation of a complete wheel embodying our invention;

Fig. 2 is a longitudinal sectional view through'the hub and a spoke, and cross section through the demountable rim; and

Fig. 3 is a detail view showing the construction of the valve stem slot.

As here shown the integrally cast art of the wheel consists of the hub 1, w ich is preferably of thereinforced type shown in our copending application above referred to, but which may be of any suitable construction to meet the requirements of the invention; and the spokes 2 which may also be of any suitable construction, being preferably, however, of the general type shown in our earlier invention, in which the spokes are characterized by their hollow formation, oval-shape in cross section, and wide outwardly-flaring curves at their ends, the curvature of the spokes at their inner and outer ends being sufficient as here shown to merge one spoke with another, and to form a continuous peripheral flange at their outer ends which serves as a support for the demountable rim.

, on the wheels.

The periphery of the casting thus formed may be finished by suitable machining operations to predetermined dimensions to provide for a suitable mounting of the rims 3, the inside diameter of the rims being made accordingly to conform to the established dimensions and thus to provide for proper relation between the parts.

In the form here shown one edge of the outer ends of the spokes, or the periphery of the integral casting comprised of the hub and spokes has an outwardly projecting rib 4 having an inwardly inclined face 4 formed thereon, the opposite edge 5 being projected outwardly and slightly inclined outwardly toward the center of the wheel to provide for readily mounting the rim on the wheel from that side. The inclined face 4* on the inward flange has a greater inclination to the wheel axis than the inclined face 5 on the outward flange.

The demountable rim 3 has a downwardly projecting rib 6 which has an inwardly inclined face 7 adapted to engage the corresponding opposite face 4 of the rib 4; and an opposite r'ib 8 which has an inwardly inclined face 9 adapted to be engaged by the upper face of a locking or binding ring 10, which is wedge-shaped in cross section, the opposite face of the ring contacting with the inclined surface 5 of the outer edge of the spokes by means of which the demountable rimis held in position on the wheel; the rim 3 is made reversible, the two inclined surfaces 7 and 9 having the same angle. Clamps 1'1 secured to the spokes by clamp bolts 12, are employed to wedge the ring 10 between the rib 8 and the surface 5 to hold the parts securely in place on the wheel. Lugs 13' and 14 which may be detachable or formed integrally with the spokes are used on opposite sides of the wheel, as here shown, to provide suitable bearing supports for the clamp bolts 12.

The demountable rim 3 may be of any suitable type adapted to the tires to be used As here shown the rim is adapted for pneumatic tires having means of well known form for mounting the tires on the rims, consisting, as here shown, of flanges 15 formed integrally with the rim, and detachable rings 16 and split lockin ring 17 whereby the tire is detachably mounted on the rim.

The valve slot is here shown in an illustrative form only. it being understood that the details of the slot construction and cooperating parts may be varied according to modifications of wheel and rim construction or of the valve stem. As here shown this feature consists of a transverse slot 18 open at one end to the edge of the spoke mounting flange 5, and having its inner end extending beyond the longitudinal center of the wheel sulficiently to provide clearance reeasso for the valve stem, the slot being located preferably substantially intermediate two opposite spokes.

As here shown, an inner depression 19 and outer depression 20 are formed in the metal on opposite sides of the slot and around its inner end to receive a slot closing clip 21 assembled on the valve stem 22 which serves to close the slot when the tire is mounted, thus forming a neat construction and excluding dirt from the inner valve connections and the tire casing.

From the foregoing detailed description the construction of our improved wheel, and its production and commercial advantages will be understood, and the importance of the invention in the general progress of this art will be recognized by manufacturers of truck wheels and by the trade.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is

1. A cast metal wheel consisting of an integrally formed hub and spokes hollow from the hub to the end of the spokes, the spokes terminating in inclined fiarages and also having solid lugs on their on s with holes extended therethrough, a demountable rim having inclined faces, one face to fit within one of the inclined flanges of the spokes, and a wedge shaped ring to fit between the other inclined flange on the end of the hollow spoke and the other inclined face of the dcmountable rim, and a bolt extending through the holes in the lugs on the ends of the spokes with a clamp at one end of the bolt to hold the wedge-shaped ring in place.

2. A cast metal wheel comprising an integrally formed hub and spokes hollow from the hub to the end of the spokes, the spokes terminating in inclined flanges, a demountable rim having inclined faces, one face to fit one of the inclined flanges of the spokes, and a wedge-shaped ring to fit between the other inclined flange on the end of the hollow spoke and another inclined face of the demountable rim, and means to hold the wedge-shaped ring in place.

3. A cast metal wheel consisting of an integrall formed hub and spokes hollow from the hub to the end of the spokes, the spokes terminating in inclined flanges, a demountable rim having inclined faces, one face to fit within one of the inclined flanges of the spokes, and a wedge-shaped ring to fit between the other inclined fiange on the end of the hollow spoke and another inclined face of the demountable rim, and a bolt extending through the-end of the s oke and having a clamp at one end thereo to hold the wedge-shaped ring in place.

4. A cast metal wheel consisting of an integrally formed hub and spokes hollow from the hub to the ends of the spokes, said spokes merging one with another at their outer ends to form continuous oppositely inclined peripheral flanges, a demountable rim having inclined faces, one face to fit within one of the inclined flanges of the spokes, and a wedge-shaped ring to fit between the other inclined flange on the end of a hollow spoke and the other inclined face of the demountable rim, and a bolt extended through the end of a hollow spoke to hold the wedge- 30 shaped ring in place.

In testimony whereof, we aflix our signatures.
